President Donald Trump blamed the Democrats for bad legislation on immigration in his recent tweet.
Separating families at the Border is the fault of bad legislation passed by the Democrats. Border Security laws should be changed but the Dems can’t get their act together! Started the Wall.— Donald J. Trump (@realDonaldTrump) 5 июня 2018 г.
Earlier in May, Trump stated that he would not give his approval to any immigration bill which would not mention a wall on the Mexican border, and slammed current US immigration laws, including the Green Card lottery, the "catch and release" policy, and chain immigration.
In March, the US Congress passed a spending bill which included $1.6 billion in appropriations to build the wall, although it was less than the $25 billion sought by the Trump administration.
